Since the double-glass components adopt a frameless design, if the fastening blocks are directly used to press the double-glass components to achieve fixation, it is easy to cause damage to the double-glass component panel; at the same time, the waterproof effect of the traditional bracket system does not meet the actual use requirements of the double-glass components. Therefore, in order to solve the above problems, a BIPV double-glass component waterproof bracket system is proposed. Utility Model Content
